Ron Paul said today he'll stop spending money on GOP presidential primaries, but will still try to obtain delegates for the national convention in Tampa.

In a statement today, the Texas congressman said he will soon outline his strategy for amassing delegates so that he can impact change within the Republican Party and go to the convention with a "strong message."

"Our campaign will continue to work in the state convention process. We will continue to take leadership positions, win delegates, and carry a strong message to the Republican National Convention that liberty is the way of the future," Paul said.

"Moving forward, however, we will no longer spend resources campaigning in primaries in states that have not yet voted. Doing so with any hope of success would take many tens of millions of dollars we simply do not have," he said.

Mitt Romney has been campaigning as the presumptive GOP standard-bearer, even though he is still short of the 1,144 delegates needed to win the nomination outright. As of today, Romney has 966 delegates and Paul has 104, according to an Associated Press tally.

Paul's supporters have recently won delegates at state conventions in Maine and Nevada. In a CNN interview last week, Paul said he's still collecting delegates so he can change the GOP's direction.

In some ways, he already has. The 2012 race has at times focused on issues such as spiraling debt and federal budget deficits -- issues that Paul has long warned about both in his previous presidential races and congressional campaigns.
